About Calib.Tools

We make camera calibration targets you can trust without measuring them yourself — and the free tools to use them well.

What we make

ChArUco, checkerboard, AprilGrid, circle grid and HALCON targets on aluminium composite and ceramic, from palm-sized boards for microscope optics to 800 × 600 mm boards for robot cells. Every pattern follows OpenCV conventions, and every target has a datasheet with its real tolerances.

How we work

  • Specs first. Tolerance, flatness and material are on the product page and datasheet before you buy, not after you ask.
  • Measured before it ships. Measured before it ships — against a golden-sample reference.
  • Files that match the board. Marker ID ranges, config files and drawings come from the same data as the target itself.

Free tools

A good target in a bad setup still wastes time. Our pattern generator, field-of-view calculator, capture planner and image checks are free, run in your browser and need no account.

Who we are

Calib.Tools LLC is a US company. We design and specify the targets, and produce them with a partner factory that measures each one against a golden-sample reference. We ship worldwide.
